09/25/2025 Contributors

Reassign the drives that previously belonged to FAS2820 node2 to node4.

Before you begin

Verify that both node3 and node4 are on standby at the LOADER prompt.

About this task

Perform the following steps on node4.

Steps

At the LOADER prompt, boot node4 into Maintenance Mode:
```
boot_ontap maint
```
The Maintenance Mode prompt appears.
Display all attached drives:
```
disk show -v
```
Record the local system ID value; this is the system ID of node4. Also record the system IDs of node1 and node2 from the "OWNER" column.
Reassign all drives from node2 to node4.
If you're using whole disks
Run the following command:

disk reassign -s <node2_system_ID> -d <node4_system_ID>
If you're using partitioned disks
Run the following command:

disk reassign -s <node2_system_ID> -d <node4_system_ID> -p <node1_system_ID>
Verify that all reassigned drives are viewable to the new system ID:
```
disk show -s <node4_System_ID>
```
If drives are not viewable, stop and contact technical support for assistance.
Verify that the root aggregate of node2 is reported in the output and the aggregate is online:
```
aggr status
```
Exit maintenance mode:
```
halt
```
